In the late 19th century, history and genealogy were somewhat popular. To satisfy the need for historical and genealogical information, several publishing companies set out to write histories of most of the counties throughout the country. This is the work that was done on Clark County. It is quite thorough. The writing is at times flowery, at other times confusing. But it is all very interesting.
